"I think Avatar is a perfect IP for an MMO. It's a very, very big world.

"Based on the first film, you might not sense that, but we're talking about an entire planet, an entire alter world, and in fact a universe that has other planetary bodies, as well, and other cultures, other life forms.

"Eventually people will see enough scope to be able to see how the MMO will work, but that's going to have to be launched… the timing of that is going to have to be carefully orchestrated with the release of the second and third film because we don't want to be giving away elements before the fact."

Avatar has already been developed into a game, however it failed both commercially and critically. Cameron stated this was simply due to bad timing.

"The Avatar game hit the street well before the movie came out and it wasn’t like an anticipated movie in the sense it was a known brand. It had to prove itself.

"And Avatar, the movie, entered the marketplace with a healthy opening but nothing resounding, nothing that certainly would have told you it was about to set the record as the highest grossing film in history. It had to prove itself in the marketplace.

"By the time it had proven itself, the videogame was kind of old news and so it under-performed, but the underperformance I think was just a release timing issue. The actual game itself I think, while it can be improved, I think they did a pretty damn good job integrating the stereoscopic experience into the gaming experience."
